INKINGV MEGHANISM FOR PRIN 'FING-PRESSES.

Speciiicaton of Letters Patent.

Application led March 19, 1914. Serial No. 825,908.

To all whom t may concern:

Be it known that I, VICTOR delphia, Pennsylvania, have invented certain Improvements in Inking Mechanism for Printing-Presses, of which the following is a specification.

One object of my invention is to provide f for feeding the ink from the tube.

Theseobjects I attain in the following manner, reference being had to the accompanying drawings, in which Y Figure 1, is a side view in dotted lines illustrating a common form of job press and showing my improved ink supplying mechanism in full lines; f.- 1

Referring to Fig. l, lis the frame of a printing press. 2Lis the mainshaft. 3 is the bed of the press to which the type form isy attached. 4 is theplaten. 5 is the ink-,distributing disk. `6 and 7 are the ink distributing rollers carried by. the frame 8, the lower portion 9 of which is shown in full lines.v The frame is pivoted at 10 and FEGLEY, a citi-l zen of the United States, residing in Philaside view of the ink the rollers 6 and 7 travel overfthe inking disk and over the type of the frame, which is held tothe bed. The above is a descrip- Patented Nov. 13, 191'?.vv

tion of an ordinary type of job printing j;

press. Y

Secured to a fixedV portion 11 ofthe press is the supporting arm 12, held thereto by a bolt 18. This 4arm carries the frame 14; be-

ing secured thereto by a bolt 14a. The bolt` Y is adapted toa slot in the arm 12 so that they frame can be adjusted thereon. Secured to the frame 14 is the main support 15 on which is mounted a notched support 16 shaped to receive the ink tubef17, shown clearly in Fig. 6. The notched support is shaped to fit the tube, as illustrated in Fig. 8,-and is held in place by projections 18 in the form of screws, which 'are located in 'recesses at the sides of the notched support.l Byv making the notched support interchangeable any size tube may be used. The largest size ink tubes maybe located directlyon the supportY 15, as in Fig. l0; being held in place byY theprojections 1S. Other supporting means for the tube will readily suggest themselves. A clamp` plate 19 extends over thetop of the tube 17, and,-in the present instance, is

firmly held to the main support `by. two screws 20. Other means of clamping may be used without departing from the essential features of the invention.

The ink tube 17 is made as slown in Figs. 6and 7, and has at one end a fixed closure 21, inthe present linstance of cork, and this closure has a small groove or grooves 22 at its .upper end, providing an outlet for-the ink. rIvhe tube is beveled at 23 on a rline with the face of the ink .distributing disk 5 so that, wheny the rollers, 6 and7 pass over the diskand over .the end ofthe tube 17,

they take up theink that is forced out of the tube by a plunger 24. This plunger 24 is made of cork or other suitablematerial andl is the closure for ,the rear end of the tube, when saidltubeis lled or purchased. Back of this plunger is a disk 25, which .is screwed onto the stem of a yblock `26.l and secured to the block by screws 27 is aring 28. Mounted inthe ringi is a head 29 of a feed screw 30.` The end ofthe head .is pointed and bears against the center of the block. The head is slightly rounded, asv

shown, so thatl should the tube be out of line with the feed screw itwill properly feed. ink in the tube. When the feedy screw is withsupplied to the ink distributing disk and,- co'nsequently, the type form will be supplied with a proper amount of ink to make theV impression. Y

The feed screw 30 has a thread extending throughout its full length and has a longitudinal key-way Y31 therein. The feed screw extends through a bearing 33 having a halfnut 34 held in place by a thumb rbolt 35. The lower portion of the opening .in the bearing is smooth while the opening in the half nut l34 is threaded to eng-age the thread of the feed screw 30 Yso that, when the feed screw is turned, it will be movedl forward, but, when the half nut is released and turned back, the feed screw can be moved longitudinally in either direction, as desired.

36 is a hub mounted on the feed screw and this hub has a key 37 which enters the keyway 31 in the screw 30, so that while the screw can be moved longitudinally in the hub it must turn therewith. The hub is held to the main support 15 by a broad headed screw 38 which overlaps the iange 39 of the hub, as shown in Fig. 5.

40 is a ratchet wheel secured to the hub 36, and this ratchet wheel has'a series ofk spring detent pawl 44 onv a Xed arm 45l projecting from the main support 15 will hold the wheel from turning backward.

In order to actuate the pawl arm from the mechanism of the press, so that it will automatically feed they ink from the tube,

the arm has a projecting pin 32 which entersy a. forked projection of the lever 46, mounted on a pivot pin 47 secured to the main frame 14 of themachine. A spring 48 is mounted on the pivot pin 47. One end of the spring bears against the'frame vand the other end bears against the lever 46, tending to force the lever against the arm 49 of a lever .50 pivoted at 51 to the frame. Thisl lever is actuated in any manner from the' mechanism of the press. in the present inl stance, it is connected by a link 52 to a lever 53 pivoted at 53a on the frame 14, and the lever 53 is in turn engaged by a lever 54 which passes freely through an ,opening in a fulcrum plate 55 projecting from the frame 1. In the present instance, the support of this fulcrum plate is a continuation of the arm 12, as indicated at 12a, and the lower end of the lever `54 bears against the portion 9 of the pivoted roller carrying frame 8 so that, as this frameV 8 is turned on its pivot to traverse the rollers over the ink distributing disk and the type, it moves away from thevarm 54 and, as it returns to the position illustrated in vF ig. 1, -it strikes the arm, causing it to actuate the pawl and to turn the ratchet wheelf40, and, consequently, to move the plunger 24 forward in the'tnbe 17 so as to project a given quantity of ink from the end of the tube. into the path of the distributing rollers. 'This operating means may he modified without departing from the essential features of the invention.

The tube 17 has a notch 56 at the rear and a plate 57 enters the notch, so as to prevent the tube from turning, insuring the beveled portion 23 being in the proper posi-V tion with respect to the ink .distributing disk 5. The clamp 19, however, holds the :tube rigidly in position.

Then it is desired to -stop the feed of the ink while thepress is in motion, I provide Va rod 58 having a head 59 which passes' through an opening 60 in the frame 14 and through a bearing 61. The .end 62of the rod, 'when it is moved to its full extent in the direction of the arrow, is in the path of the arm 'Opand prevents themovement of the arm and, consequently, the movement of the pawl carrying arm 41. The rod 58 has a notch, as shown in F ig. :3, forming ashoulder 63 which, when it passes .through the opening 60 in the frame 41, .engages the upper wall .of the opening due to the spring 64 which bears upon the underside of the rod and forces it up, thus holding the rod in its projected position, but, as'soon as the rod 58 is forced down and pulled back, the mechanism will be allowed to feed ink again from the tube. i

nlorder to regulatethe movement ofthe lever 46,:which controls the pawl rcarrying arm, Iprovidea block'65, the round en d of which forms a stop for the lever 46:as it movesk back after feeding the .wheel :forward. The arm has an eccentrically curved surface 66 and the block can be moved. for-V ward by a screwv which passes'through a threaded 1 opening in a portion 68 of" the frame.' Y There is a thuinbehold 69 0n the end of the Lrod G'Tby which it is turned so that by adjusting the bleek to any position with respectto the curved surface 66, the vmovement of the arm 46 can be regulated, conse? quently, the amount of ink discharged from the end of the tube is controlled.k i

In order to accurately adjust' the end 23 of the tube to the ink distributing disk 5, I form an extension 70, which projects downwardly from the frame 14e and has a set screw 7l at its lower end which bears upon a portion of the frame of the press. This set screw is held in its adjusted position by a jam nut, as shown in F ig. l. By turning the screw the end 23 of the tube can be raised or lowered, so as to be brought into proper alinement with the ink distributing disk. Y

As illustrated in Fig. 2, the tube is preferably located at one side of the center of the press, so that the ends of the distributing rollers will receive the ink and will distribute it onto the disk near its periphery; thus an even distribution of the ink thereon is assured, and, as the rollers take up the ink and distribute it onto the type form each portion of the form will be provided with the proper quantity of ink and, as the feeding mechanism continuously supplies a given quantity of ink, each impression will be supplied with the same amount of ink.

By locating the operating lever 5l, for my improved mechanism, in position to be actuated by the frame 8 carrying the rollers, it is automatically thrown out of action when the impression lever is moved to move the bed and inking mechanism of the press from the normal position to prevent the paper contacting with the type, consequently all unnecessary inking of the rollers is avoided and the mechanism is only in operation when the impression is being made.

I claim 1. A tube for supplying ink to printing presses consisting of a casing of an even diameter throughout and having one end beveled; a plug forming a closure for the beveled end of the tube and also beveled, said plug having a groove therein at the beveled portion communicating' with the interior of the casing so as to allow for the esca-pe of ink from the tube; a plunger tightly fitting the tube and forming a closure for the opposite end thereof and arranged to be moved forward in the tube so as to discharge a given quantity of ink through the groove in the plug.

The combination in means for supplying ink to printing presses, of an ink distributer; a tube containing ink and having an opening through which the ink escapes, said opening being so located that the ink distributer will receive ink from the tube as it escapes through the opening; means for supporting` the tube; a plunger; a feed screw having a longitudinal slot therein for feeding the plunger forward; a bearing having a threaded portion engaging the feed screw; a hub having a key therein entering the longitudinal slot in the feed screw; a ratchet wheel secured to the hub; an arm loose on the hub; a spring pawl carried by the arm; and means for actuating the arm on the movement of the press.

3. The combination in means for supplying ink to printing presses, of an ink distributer; a tube containing ink and having an opening through which the ink escapes, said opening being so located that the ink distributer will receive ink from the tube as it escapes through the opening; means for supporting the tube; a plunger; a feed screw having a longitudinal slot therein for feeding the plunger forward a bearing having a threaded portion engaging' thefeed screw; a hub having a key therein entering the longitudinal slot in the feed screw; a ratchet wheel secured to the hub; an arm loose on the hub; a spring pawl carried by the arm; a pivoted lever engaging the pawl carrying arm; means for limiting the movement of the lever; and lever mechanism engaging the pawl actuating lever, said lever mechanism being actuated on the movement of the press.

et. The combination in means for supplying ink to printing presses, of an ink distributer; a tube; means for securing the tube in position, said tube having an opening at one end; a plunger in the opposite end of the tube; a feed screw having a block with a screw threaded stem; a disk fitting the tube and mounted on the stem; and means for actuating the screw to feed the plunger forward, the disk being detachable so that, when tubes of different sizes are placed in position, the disk can be removed and another disk substituted therefor.

5. The combination in means for supplying ink to printing presses, of an ink distributer; a tube containing ink having an opening at one end; a plunger at the opposite end of the tube; a disk fitting the tubev back of the plunger; a block having a screw threaded stem engaging the disk; a feed screw; and means for actuating the feed screw, said feed screw having a head at its outer end and being loosely mounted in the block, said head having overhanging portions preventing the withdrawal of the head from the recess in the block, the block having a free movement on the head.

In testimony whereof, I have signed my name to this specification, in the presence kof two subscribing witnesses.
